I just bought this ECU hoping it would fit in my S4Rs but it runs to rich. I took it to the dyno and it idles at 11 to 12 fuel to air ratio. I guess it needs the 54mm throttle bodies to run right.
I am looking to sell it for $600 but will entertain offers.
This is the control unit for after market 54mm exhaust and air box. (IAW 59m.A8)
If you have any after market exhaust on any 999 and are looking for more fuel to maximize that power, this is the computer.
I will also make a trade for anyone who happens to have a performance ECU made for a monster s4rs.
